The Pacific Tsunami Warning Center (PTWC) said late Friday in U.S. time that tsunami danger from the Vanuatu quake had ended, revising its preliminary magnitude estimate to 6.9 from 7.2.
PTWC issued its final bulletin at 11:28 p.m. ET Friday, Oct. 23 (03:28 UTC Saturday, Oct. 24). Its initial bulletin, issued at 10:37 p.m. ET Friday, had put the quake at magnitude 7.2.
The first notice warned that dangerous waves could reach parts of Vanuatu’s coast up to 300 kilometers from the epicenter; EconoTimes’ earlier report on the initial alert covered the warning. PTWC said small changes in sea level could continue near the quake for several hours.
The U.S. Geological Survey lists the earthquake at magnitude 6.9, a depth of 10 kilometers and 197 kilometers west-northwest of Port-Olry.
Separately, Hindustan Times reported that Vanuatu authorities canceled their local alert after the National Disaster Management Office had advised coastal residents to move to higher ground.
